What I'm looking for

I seek product roles where I can lead API- and data-heavy B2B SaaS or AdTech products, collaborate cross-functionally, and drive measurable performance and UX improvements.

I am a Scrum-certified Product Owner with experience across AdTech and B2B SaaS, focused on complex API- and data-intensive products. I bridge business goals, technical constraints, and user experience, driving measurable improvements in performance, reliability, and operational efficiency.

I have led high-impact deliveries used by 1,500+ clients, redesigned legacy workflows to boost performance by 75%, and reduced bug resolution time from 20 to 5 days. I combine product strategy, user research, KPI-driven prioritization, and close cross-functional collaboration to deliver scalable, user-centered solutions.
